Chapter 4 Deployment & Installation
Once you are familiar with the basic operation of the radios you are ready for deployment in the field. The deployment process
consists of the following steps:
•
Site Selection
•
Site survey at MU and RU sites
•
MU installation
•
RU installation and antenna alignment
•
Link test
Site Selection
Proper site selection for your MU will help ensure a successful deployment. Site selection will depend on a wide variety of
factors, but from the radio’s performance standpoint, please consider the following:
•
Path from MU to RU should provide unobstructed line-of-sight (LOS), thus it is advisable to place MU as high as
possible on a tall building or tower.
•
Ethernet cable limit is 100 meters from Ethernet device (router, switch) to radio.
•
Radios should never be deployed without proper grounding.
•
Consider nearby sources of interference that could degrade the performance of the radio. Mount radios as far from
sources of interference as possible.
Site survey
The radios provide an on-board site survey tool which measure the average and peak noise levels on any given channel.
To use the survey tool, the radio must be in Opmode “OFF.” The survey can be performed for any specified amount of
time (in seconds), and for either the horizontal or vertical polarization.
Prior to performing the site survey, place the radio in the installation spot, and aim the radio in the desired direction.
After the specified period, the results of this command will provide you with a listing of each channel in the band, the
average signal received, and the maximum signal received during the survey period.
Example:
#> survey
Press any key to stop.
noise floor (peak/avg dBm) rssi by pkt (peak/avg dBm)
0> -97 / -98 n/a
1> -97 / -98 n/a
2> -97 / -98 n/a
3> -97 / -98 n/a
4> -97 / -98 n/a
5> -97 / -98 n/a
6> -97 / -98 n/a
7> -97 / -98 n/a
8> -97 / -98 n/a
Ch 1 h 5260 --> -97 / -98 n/a
Success.
Channel Planning
Based on the results of the site survey at each end of the link, choose a channel which offers the lowest noise floor. In order to
reliably operate in the higher speed modes, clean spectrum is essential.
